VENTILATING WINDOW-HINGE.

' Specification of Letters Patent. PatentedJan, v11, 1921 Applicationfilled January 15, *19197.` Serial No. 271,188.

To all whom t 'may concern Be it known that I, E BLAKE SHAND, citizen ofthe United States, residing at Detroit, county of Wayne, State ofMichigan, have invented a certain new and useful Improvement inVentilating yTindow- Hinges, and declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it pertains to make and use the same,reference being had to the accompanying` drawings, which form a part ofthis specinication.vv y

My invention relates? to a window ventilating` hinge shown intheaccompanying drawings and more tutrticularlyy described in the followingspecification andclaim..

Primarily the object of my invention is to provide a device whereby theupper or lower sash of a slidable window maybe swungtinwardly forpurpose of ventilation g-or when it is desired to clean the window.

With the foregoing and other objects in l'iew which will appear as thedescription proceeds, the invention resides in the combim nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment of the invention herein described withoutdeparting from the spirit of the same.

in the drawings forming part of this specification Figure l is afragmentary vertical sectional view through the lower portion of awindow sash and its supporting casing;- showing the sash in a verticalposition with the cup-shaped member of the hinge lodged in a mortiseformed in the side frame of the sash-showing also the co-acting memberof the hinge attached to the wall of the window jamb.

Fig. 2 isa similar sectional view, the inner stop and also the partingstop being first removedgshowing the upper and lower sash swung to ahorizontal position and resting upon the window stool in position forcleaning.

Fig. 3 isa fragmentary perspective view of a window casing, showing onemember of the hinge secured to the jamb.

Fig. 4 is a fragmentary perspective view of a window sash showing theother member of the hinge secured in a mortise formed in the sash frame,also indicating a fragment of thesash supporting ribbon, in turn securedto the usual sash cord. l

F 1g. 5 is a vertical sectional view through the sash frame and windowjamb on line 5 5 of Fig. l.

Referring now-to the letters of reference placed upon the drawings l iA, denotes a window frame. y dow `jamb. k@indicates the inner`detachable` stop. D, the parting stop, a. portion D1 of which isremovable.y D2 is a `spring secured to the endof the removablesectionadapted to 'beari against the abutting end of the xed portion oftheparting stopto force the lower dovetailed end D3, of the removablesection into contact ,with lower fixed portion of the in Fig. 3.

Respectively securedto the window jamb and lodged in a mortise formed inthe side frame of the window. sash are members parting stop, as` shown-which cooperate lto forma hinge whereby the sash may be tilted at anangleto its usual vertical position in order ltoprovide for ventilation,or the sash may be swung into a substantially horizontal position forcleaning the glass.

yIn carrying vthis' into effect, E, denotes a projecting stud(constituting one member of the hinge) which is preferably elliptical inform and constructed of sheet metal with an aperture to receive a screwF, whereby the stud may be secured to the jamb. E1 are projecting pointsadapted to enter the wood to prevent the stud turning upon the shank ofthe screw.

G, is a cup-shaped element (constituting the coperating member of thehinge) provided with a channel G1, opening into the cup-shaped portionof the member. The ele-A ment G is lodged in a mortise cut in the edgeof the side members of the sash frame andis secured therein bya screw H,extendinginto the Wall of the sash. The open channel portions of thecup-shaped elements of the upper and lower sashes are offset forwardlyfrom the centers of the said cupshaped elements, and the studs E whichco- B, the wmf.

operate with the cup-shaped elements are are swung downwardly to ahorizontal position, are adapted by means of the rsidewise play of thecup-shaped elements over them` to permit the lower sash to rest fiatupon thebottom of the window frame or casing and the upper sash to restupon the lowerv sash as illustrated in Fig. 2 of the drawings.

I, designates a metallic ribbon pivoted at I1, to the edge of the sashand secured at its uppery end to the usual sash cord J.

Having indicated the several parts by reference letters, theconstruction and operation of the device will be readily understoodz-llhen it is desired to tilt the lower sash for purposes ofventilation, the inner stop-C, is first removed and the sash swunginwardly and secured by a suitable fastening device, forming the subjectmatter of another patent. If the windows are to be washed, the sash isswungdown to a horizontal position so as to rest upon window stool;-theupper sash may also be lowered and swung into a horizontal position soas to rest upon the lower sash, upon first with drawing the removableportion of the parting stop, D1, yasY shown in F ig. 2 of the drawings.

The removable portion, of the stop D, is held in place by the pressureof the spring D2, forcing said removable section against the end of thelower section, when the sash is in its usual position, as has beenpreviously explained.

It will be noted that the length of the stud E, is greater than thewidth of the channel G1 leading into thecup-shaped element and while itis adapted to freely enter the cup-shaped element when the sash is fmoved vertically, it forms a secure pivot for the sash upon the latterbeing tilted due to the length of the stud being greater than the widthof the channel portion of the co` acting cup-shaped element. y

Having thus described my invention, what I claim is In a device of thecharacter described the combination with a window frameor casing andupper and lower sashes of cupshaped elements embedded in the sashes andeach having an open channel portion leading to the interior of the saidcup-shaped element and offset forwardly from thel center thereof, andcooperating studs secured to the window frame and offset forwardly fromthe centers of the guideways thereof and adapted to enter the saidcupfshaped elements by way of the channel portions when the sashes arein a vertical position and being of a size to lie off center of saidcup-shaped elements when the sashes are swung downwardly to a horizontalposition to provide for sidewise play of the cup-shaped elements overthe studs to permit the lower sash when vin the said horizontal positionto drop and rest on the bottoni of the window frame or Casing and theupper sash to rest upon the lower sash.

In testimony whereof, I sign this specifican tion in the presence of twowitnesses.
